, Zoning cylinder also called sub-Drum, it is essential steam boiler ancillary equipment, is widely used in the power generation, petrochemical, iron and steel, cement, construction and other industries. Second, the performance of structural sub-cylinder is the main equipment of the boiler, the steam generated in the boiler operation assigned to go separate ways pipeline, sub-cylinder based pressure equipment is a pressure vessel. Sub-cylinder's main function is to distribute steam more than one seat on the sub-cylinder connected the main steam valve and steam distribution valve, at the sub-cylinder steam points to the need to. Sub-cylinder pressure components: Steam Distribution seat, main steam valve seat, safety door seat trap seat, pressure gauge, Block, Block thermometer; head, shell, flange material are Q235-A / B , 20g, 16MnR, specifications ф159-ф1500, working pressure for 1-2.5MPa, working temperature: 0 ~ 400 ℃, working medium: steam, hot and cold water, compressed air. Special specification model design can be arranged according to user requirements. Technical specifications when the medium is steam, provisions should be "Pressure Vessel Code design, and to determine the cylinder diameter, material and thickness, the general principles: cylinder diameter is the largest take over the diameter of 2-2.5 times, can be generally The cylinder body fluid flow rate to determine the material 10-20 # seamless pipe, Q235B, 20g, 16MnR plate rolling, to take over the number determined by the engineering design. Ordering Information, flow, pressure, temperature parameters. 2, into the steam out of steam, drains diameter, number of 3, whether the requirements of sub-cylinder sizes. 4, if you want to gauge, temperature gauge, safety valve.
